The fleas are terrible in my yard, too, and the vet told me I could give them Frontline every 3 weeks instead of just once a month, so that is waht I do. But I would not do this for long-term. I'm moving in 2 weeks so applying the Frontline every 3 weeks is definately a short-term solution for me. I would treat your yard and your home if I were you. |
